@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.execute(shellCommand, callback);

@param localScriptFile - localScriptFile

@param remoteFileLocation - remoteFileLocation
@param options.vars - templateVars
@param optiosn.progressBar - show progress bar
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.copy(localFile, remoteFileLocation, options, callback)
